Pulled the TPS out this weekend and tested it as svx_commuter recommended. Very cool How to !!!

Anyway, I definately have a bad TPS. My measurements consistently shows large spikes between 5 TPS increments (resistance should go up only 10 ohms but actuially spikes in 50 ohm increments). This happens early in throttle opening . After that I have about 10 increments where the resistance flatens then actually goes down! As svx_communter says "That's not supposed to happen"! Your supposed to see a steady rise in resistance...never a drop or area of no change.
Good luck!
